Chemical Structure
Description
[3-(4-Fluorophenyl)-5-methyl-7-oxo-7H-furo[3,2-g]chromen-6-yl]acetic acid (CAS 664366-13-6) is a high-purity analytical reference standard with the molecular formula C20H13FO5 and a molecular weight of 352.31 g/mol.
The molecular framework of [3-(4-Fluorophenyl)-5-methyl-7-oxo-7H-furo[3,2-g]chromen-6-yl]acetic acid (C20H13FO5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
